1.	The perimeter of a square is 28.2 m . Find it's area ?
Answer» rong>SOLUTION :- Given , Perimeter of SQUARE = 28.2 m We need to find , Area of square = ? As we KNOW that , ♦ Perimeter of square = 4 × side Method of solving :- By SUBSTITUTING the value of perimeter of the given square & by simplifying it we can have the value of side . So , as we know that Area of square = Side² , by substituting the value of side we can have the area of square . Simplification :- Firstly finding the side : → Perimeter = 4 × side → 28.2 = 4 × side [ °.° 4 transposed to RHS to LHS ] → 28.2 ÷ 4 = Side → Side = 7.05 m Now , by substituting the value of side in area of square ⇒ Area = Side² ⇒ Area = ( 7.05 )² ⇒ Area of square = 49.7 ≈ 50 Note :- This symbol ‘≈’ means approximate value of that number . Hence , area of square = 49.7 approximately equal to 50 .

Answer»

Given ,

We need to find ,

As we KNOW that ,

♦ Perimeter of square = 4 × side

Method of solving :-

By SUBSTITUTING the value of perimeter of the given square & by simplifying it we can have the value of side . So , as we know that Area of square = Side² , by substituting the value of side we can have the area of square .

Simplification :-

Firstly finding the side :

→ Perimeter = 4 × side

→ 28.2 = 4 × side

[ °.° 4 transposed to RHS to LHS ]

→ 28.2 ÷ 4 = Side

→ Side = 7.05 m

Now , by substituting the value of side in area of square

⇒ Area = Side²

⇒ Area = ( 7.05 )²

⇒ Area of square = 49.7 ≈ 50

Note :- This symbol ‘≈’ means approximate value of that number .

Hence , area of square = 49.7 approximately equal to 50 .
